• When you input a 10 V signal, the frequency reference will be 200%.
• When you input a 5 V signal, the frequency reference will be 100%.
When you input a 5 V or more signal, E1-04 [Maximum Output Frequency] will limit the drive output and the
frequency reference will be 100%.
• When you input a 0 V signal, the frequency reference will be -25%.
• When you input a 0 V to 2 V signal, the frequency reference will be 0%.
• When you input a 2 V to 10 V signal, the frequency reference will be 0% to 100%.
